首次使用列表项 单击“文本颜色不更改”

Question

我在片段中有一个自定义列表视图，并且在项目单击文本颜色更改和选框运行时，但是在第一次项目单击时没有任何工作，没有选框或没有文本颜色更改，第二次单击两者都工作正常。请帮忙！！

mainListViews.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                textView = (TextView) view.findViewById(R.id.textView);
                String text = textView.getText().toString();
                song_namef.setText(text);
                setItemNormal();
                View rowView = view;
                views=rowView;
                setItemSelected(rowView);
            }});
public void setItemSelected(View view){
    View rowView = view;
    TextView tv = (TextView)rowView.findViewById(R.id.textView);
    tv.setTextColor(Color.WHITE);
    tv.setEllipsize(TextUtils.TruncateAt.MARQUEE);
    tv.setSingleLine(true);
    tv.setHorizontallyScrolling(true);
    tv.setSelected(true);
    tv.requestFocus();
}
public void setItemNormal()
{
    for (int i=0; i< mainListViews.getChildCount(); i++)
    {
        View v = mainListViews.getChildAt(i);
        TextView txtview = ((TextView)v.findViewById(R.id.textView));
        txtview.setSelected(false);
        txtview.setSingleLine(true);
        txtview.setTextColor(getResources().getColor(R.color.tabsScrollColor));
    }}
